Application tiled August 29, 1924. Serial No. 735,014.

My invention relates to improvements in slide construction, having to do wlth the operating of interlocking fastener devices of the form that. are used for the closlng and opening of gaps in garments, shoes, Arctic overshoes, and in pouches and the like, one form of whichl is shown and described in my `application that was filed April 28, 1924, Serial No. 709,643, and the object of my improvement is to produce a slide for engaging and disengaging the active elements of such interlocking devices that is relativel simple in form and convenient and eentin use.

In the accompanying drawing v Figure 1 is a front elevation of my improved slide as a plied to a setof interlocking fastener devices mounted on a pair of strips of fabric that represent the two sides or borders of a gap in a garment structure or pouch, the parts being assumed to be in a vertical position.

Figure 2 is a similar View of the slide only with the front or top plate thereof broken away, showing the ^divergent channels for the fastener devices.

Figure 3 is a side elevation of the slide.l

Fig. '4 is a top plan view of the same.

Figure 5 is a plan of the blank for `the main part.

Figure 6 is a similar view of the s ame with the guide wings bent to the operating position and the strengthening ribs indicated by broken lines.

Figure 7 is a view of the clamp piece.

Figure 8 is a sectional view on an enlarged scaleon the line 8 8 of Fig. 4:.

Y My improved slide is used with a set of interlocking fastener devices 10 that have tions 11 that are arranged in series and are brought to Ythe engaging position and are disengaged one from the other by a longitudinal movement of the slide, which is designated as a whole by the character 12. The devices 10, as shown, are mounted and arranged in .two series on the two opposed and adjacent sti'ipsc13 of fabric.

For manipulating the slide there is provided a disc-like handle, pull device oriinger-andthumb piece 14 that is normally in dependent position and is pivotally connected to the slide proper. As shown, the handle or pull device 14 has at' its upper end a, tail-hke extension 15 that has a per- Intermediate said lower overlapping and interengaging active porforatien 16 for receiving a hook 17 that is disposed substantially midway of the length v holding the handle 14 in place, serves as the means for maintaining the substantially parallel relation of the top and bottom or front and rear plates of the main part 20.

To this end, said clamp piece or yoke 19 -is generally of Ushape,compris1ng the Y mentioned and the f rear arm 21, and t e curved connecting front arm 18 alread member 22. The opposed edges 23 of the gap or open space between the arms 18 and 21 are straight and parallel, andengage iin-v dividually with the outer faces respectively of the front plate 25 and the rearplate i26. Said plates 25 and 26 may be provided, asl shown, with longitudinally directed strengthening ribs 27 and 2'2` that are formed by suitably indenting the sheet of metal of which the main part is made.

The top and bottom plates and 23 are of suitable area and are spaced suitably to provide between them the two channels 28 that serve as the ways for the active ortions 11 of the fastener devices 10 and w ich channels, asis usual, combine to form 'a substantially Y-form. That is to say, the lower portions 29 of the channels 28 may be said to be merged, corresponding to the position in which the activelocking elements v11 are interengaged, and the upper 4portions 39 thereof are divergent, corresponding to the disengaged position of the elements, 11. portion 29 and the upper portions 30 the active elements 11 are more or less forcibly acted upon by the slide 12 to effect the interlocking and disengagement thereof.

As shown, the-lower plate or bottom plate 26 is substantially iiat or plain, except for the strengthening rib 27, .and the upper plate 25 has the body portion fiat or plain, except for the strengthening rib 27, and is bordered along the lateral edges 31 with dependent ilanges 32 that form the outer vwalls of the channels 28.

Bivergent walls 33 are provided adjacent the upper ends of the channels 28 that form the border walls of the upper. portions'30 of said channels 28 on the inner sides thereborder walls for the same. with relation to the front plate 25 and the` of. That is to sa regarding said' upper portions 30 as in ividual channels in the broad sense, the divergent walls 33 serve as As to location rear plate 26 or to the structure of the slide generally, the particular walls 33 are located along the inner sides of the individual chan-4 `nels 30. operatively, said divergent walls 33 function when the slide 12 is moved in the downward direction for disengaging thev fastener devices 10 by makng'contact with said devices 10 successively, the two opposed and adjacent wallsA 33 combining to form a wedge-like structure, as will be noted from Y inspection of Fig. 2. l

In functlomng as described, said walls 5 33 serve virtually as the end ot a substantially Y-shaped channel structure -and the other two walls of said channel structure are provided by the portions of the front i lines 36 show the connections with the wings or walls 33.

. i Solder is used to hold the clamp piece 19.

in place.

The clamp iece 19 is positioned so as to n-like structure relatively to t e neck 34 and adjacent portionsl of the front and rear plates 25 and 26.v

A relatively compact structure is edected by entering the yoke 22 into a slot 37 that .extends vertically across the neck 341 and 1.a short distance along the adjacent portion of the front and rear plates 25 and 26. Shoulders y,38,provided at the ends ot -the active engaging edges 23 ol the arms 18- and21 engage with the end walls 39 ot the slot 37.

` As described, the clamp piece is plain and flat and makes edgewise contact with the opposed .front 'and rear plates. Also, the

hook 17 is disposed .edgewise-to theconnec in tail 15 of the handle.

e overlapping and interengaging active portions 11 are constructed after the mer of those shown in the application referred to afnd of the particular form that involves the use of a pair of coil springs that are swaged or shaped to improve thelocg effect, such swaging being diderent" tor the two sides. A

The left active members 11, having reference to Fig. 1, are part ot aspring 40 Athat is threaded along e border or edge portion 41 of the fabric 13.l The adjacent active Lerares portions 1l are interconnected by the portions l2 ot the spring t@ that aretaded through the tabric 13.

The spri are wound on a cylindrical arbor and are swaged in any meer that to will produce active members 11 that will have improved hol plain circular torni for the convolutions. To this end, as shown, the active ortions qualities over the 11 ot the right spring 40a, Vwhich is t readed 75 on the fabric border 41,- has downwardly directed hook-like ends t3 that enter slightly though appreciably into the mating convolutions ot the lett active portions 11.

The connecting portions 42 serve tointerconnect the right active portions ll and Yare the parts ofthe spring 40 that are threaded through the fabric border 41a.

Clips of any suitable torm are provided that serve to limit the movement ot the slideand are also adapted to secure the ends ot the, springs 40 and, l0 and to position the parts relatively to the fabric 13.

,'llhus at the lower ends of the srings a single clip or stop d4 is used and at e upper ends are the individual clips or stops t5.
